As a typical nonclassical state, the squeezed state [1]}, [2]}, [3]} is of significant importance since it possesses a quantum noise which can be below the shot noise level (note that a coherent state corresponds to the shot noise) [4]}, [5]}, [6]}. As a consequence, the squeezed state can improve the signal-to-noise ratio (SNR) [7]}, [8]}, [9]} and has been utilized in numerous applications, such as, quantum-enhanced magnetometer [10]}, [11]}, gravitational wave detection [12]}, [13]}, [14]}, and quantum imaging using only conventional lenses (without any scattering lens) [15]}, [16]}, [17]}, [18]}, [19]}, [20]}, [21]}.
